  liar paradox
  
     <philosophy> A sentence which asserts its own falsity,
     e.g. "This sentence is false" or "I am lying".  These
     paradoxical assertions are meaningless in the sense that there
     is nothing in the world which could serve to either support or
     refute them.  Philosophers, of course, have a great deal more
     to say on the subject.
